Uniform Energy Bound for Maxwell-Higgs Equations on Reissner-Nordström Spacetimes

In this paper, we prove the uniform energy bound for the Maxwell-Higgs system in the exterior region of Reissner-Nordström black holes. By employing an integrated local energy decay (ILED) estimate in combination with the Sobolev embedding theorem on a compact Riemannian manifold, we derived $L^{\mathrm{\infty }}$ bounds for the fields. These results were then used to obtain a bound for the conformal energy of the system using the Cauchy-Schwarz inequality and Hardy-type inequalities.
